Lawmakers want tougher carbon-reduction goals, even as WA falls short of current targets
Citing the latest scientific research, Gov. Jay Inslee is urging legislators to adopt a more aggressive course for curbing emissions. by Shauna Sowersby / January 17, 2020 Piles of wood chips sit near the RockTenn paper mill in Tacoma, June 1, 2016. State measures to limit greenhouse gas emissions from large polluters, including the mill, aren’t -
Installing air filters in classrooms has surprisingly large educational benefits
$1,000 can raise a class’s test scores by as much as cutting class size by a third. By Matthew Yglesias@mattyglesiasmatt@vox.com An emergency situation that turned out to be mostly a false alarm led a lot of schools in Los Angeles to install air filters, and something strange happened: Test scores went up. By a -
The toxic killers in our air too small to see
Current pollution meters don’t count the very smallest pollutants – nanoparticles. Recent research suggests these tiny toxic substances could be a major cause of illness and death. By Tim Smedley 15th November 2019 A After years of headlines about air pollution, we’ve been misled on a few things about the world’s biggest environmental health problem. -
The Guardian, Carbon calculator: how taking one flight emits as much as many people do in a year
Even short-haul flights produce huge amounts of CO2, figures show Niko Kommenda Fri 19 Jul 2019 09.05 GMT Taking a long-haul flight generates more carbon emissions than the average person in dozens of countries around the world produces in a whole year, a new Guardian analysis has found. The figures highlight the disproportionate carbon footprint of -
Novel cardiovascular risk factors: air pollution, air temperature, pain, and sleep duration
For the podcast associated with this article, please visit https://academic.oup.com/eurheartj/pages/Podcasts. Traditionally, we have used age, gender, body mass index, blood pressure, lipids, smoking, and diabetes to assess cardiovascular (CV) risk. However, up until recently, the CV risk provided by environemental hazards such as pollution,1–3 noise,4–6 temperature,7 sleep duration8, and air quality,9,10 among others, have been -
Emissions from planes and ships: facts and figures (infographic)
Greenhouse gas emissions from international aviation have more than doubled over the past two decades, while those from shipping have also increased. Check out our infographics. Although international aviation and shipping each account for less than 3.5% of the EU’s total greenhouse gas emissions, they have been the fastest growing sources of emissions that contribute -
2019-04-17Estimated long-term (1981−2016) concentrations of ambient fine particulate matter across North America from chemical transport modeling, satellite remote sensing, and ground-based measurements
Researchers estimated historical fine particulate matter (PM2.5) air pollution levels across North America from 1981 to 2016 by combining satellite data, computer modeling, and ground-based measurements. The study found that average PM2.5 concentrations fell dramatically over the period, dropping from 22 μg per cubic meter in 1981 to about 7.9 μg per cubic meter in 2016. While this research focuses on air quality rather than airport noise, it provides a scientific framework for tracking long-term environmental exposure trends relevant to public health policy. -
Guardian: Air pollution is the ‘new tobacco’, warns WHO head
Exclusive: Simple act of breathing is killing 7 million people a year and harming billions more, but ‘a smog of complacency pervades the planet’, says Dr Tedros Adhanom -
2018-02-07Aviation-related impacts on ultrafine particle number concentrations outside and inside residences near an airport
A study of residences near Boston's Logan International Airport found that jet engine exhaust significantly raises ultrafine particle concentrations both outdoors and indoors, with levels roughly 1.7 times higher when winds blow from the airport's direction. Researchers monitored 16 homes located 4–6 km from the airport and confirmed that aviation-related particles penetrate inside residences, posing potential health risks to nearby communities. While focused on Logan Airport, the authors note these findings are likely applicable to other major airports, including those in dense urban areas.
